Monitors traffic load on network links

The MultiRouter Traffic Grapher uses SNMP to read the traffic counter of your router; it then logs the traffic data and creates graphs (which are then embedded into Web pages) representing the traffic. MRTG creates daily, last seven days, last four weeks, and last twelve months's views; it can do this because it keeps a log of all the data it has pulled from the router. This log consolidates automatically, so that it doesn't grow but you still see all the relevant data for all the traffic over the last two years. This is all done efficiently enough to monitor 200 or more network links at once. MRTG can monitor any SNMP variable you choose, not just traffic level. You can even use an external program to gather the data to be monitored. People are using MRTG to monitor system Load, Login Sessions, Modem availability and more. You can even combine two or more data sources into a single graph.
